Bacillus  neidei  Nakamura, Shida, Takagi and Komagata 2002.

Phenotypically very closed to
Bacillus fusiformis, Bacillus pycnus and Bacillus sphaericus, and separable from these species by
growth factor requirements, several substrate oxidation , decomposition tests, and differences in fatty acid compositions.
Gram-positive, 1.0 x 3.0-5.0 µm, motile rods. Occur singly or in chains. Produce
terminally, spherical endospores in swollen sporangia.
Colonies are  circular, thin, smooth, entire, 1.0 mm in diameter.  On R2A agar Difco
develop a green pigment. Aerobic. Moderately acidophilic. Grow at pH 5.7-7 and in 0-
5% NaCl. Optimal growth temperature is 28–33  ºC. Growth occurs at 5 and 45  ºC
(variable),  not at 4 or above 45  ºC. Allantoin or urate are not required. Biotin, thiamine
and cystine are required.
Isolated from soil. Susceptible to chloramphenicol, tobramycin, streptomycin, erythromycin and tetracycline.
No growth in the presence of lysozyme (0.001%).
Undetermined.

Positive results for catalase, hydrolysis of gelatin & acid production (after 14 days
incubation) from fructose.

Negative results for degradation of tyrosine, hydrolysis of urea, egg yolk reaction, oxidase, indole, H
2S, nitrate reduction, hydrolysis of
casein, hydrolysis of starch, Voges-Proskauer, citrate utilization, acid production (after 14 days incubation) from: L-arabinose,
